Yellow Convict fry !!

Today I was amazed to see my Yellow convicts swim around the tank with school of tiny babies. I though they had eaten eggs but I was wrong. They must had hidden eggs some where else. There are like 100 tiny Yellow convict fry swimming around with their parents. I think this has become a nightmare to the Cory dora and Cribansis female who lives in that tank. Yellow convict parents are very aggressive towards them and attack them when ever they comes out of their hideouts among plants. I want to remove them but its impossible to do without disturbing the Yellow Convict fry. The fry has passed the wiggler stage and they are swimming and seems big. They seems grow fast !
